1Cust742.an1.nyc41.da.uu.net == 63.24.130.230
which is like:
22Cust55.tnt13.tco2.da.uu.net. == 67.206.50.55
*Cust***.DEV.HUB.da.uu.net == dialup user ip. Most times ppp customer,
most times a /24 (or like) per DEV... So, unless someone is logged in at
this time to: 63.24.130.230 there isn't anything to get to...

'their network' I think is the problem for them, again I'm not a VZ
employee (yet?), but I'd bet they have several hundreds of blocks for DSL,
several DIAL providers and distributed smtp acceptance points for their
customers... It seems that SMTPAUTH would be a decent way to get this
resolved though (or ONE decent way).
